Abstract (en)
The embodiments of the present invention disclose an array substrate, a liquid crystal display panel and a display device. Low temperature compensation circuits one-to-one corresponding to the data lines are added to the peripheral area of the array substrate; each low temperature compensation circuit comprises a first branch and a second branch connected in parallel; wherein the first branch comprises a divider resistance; the second branch comprises a diode and a capacitance connected in series; in the second branch the position of the diode and the position of the capacitance can be interchanged. Since the voltage difference between the both terminals of the diode rises with the temperature decreasing, the voltage difference on the route comprising the diode and the capacitance rises when the temperature decreases; a divider resistance is used in the route to divide the voltage of the voltage signal inputted at the data signal receiving terminal, reducing the voltage signal inputted to the input terminal of the data line. The reduced voltage signal brings a higher transmittance, compensating the integral shift of the voltage-transmittance curve in low temperature environment, such that the voltage-transmittance curve at low temperature is kept in accordance with that at normal temperature.
